fix(automations): restore automation deletion

[arnestrickmann]

Description

Restore automation deletion by closing the modal detail sheet before opening the global confirmation dialog. The sheet previously made sibling portals inert, preventing interaction with the confirmation action.

The selected automation is retained while the sheet closes, and its details reopen if confirmation is cancelled or the delete request fails.

Checklist

• I kept this PR small and focused
• I ran a self-review before opening this PR
• I ran the relevant local checks or explained why not
• I updated docs when behavior or setup changed
• I added or updated tests when behavior changed, or explained why not
• I only added comments where the logic is not obvious
• I used Conventional Commits for the commit message and PR title

No automated test was added because the regression depends on interaction between separately portaled Base UI modal layers; the behavior was verified in the Electron app.
